Wire Spraying

Definition - What does Wire Spraying mean?

Wire spraying is one of the processes of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc is generated between them. The heat from this arc melts the incoming wire, which is then sprayed via air jet from the gun. This entrained molten feedstock is then deposited onto a substrate.

Corrosionpedia explains Wire Spraying

The thermal wire spray coating processes involves the deposition of coatings from a stream of high-velocity finely divided particles in a molten or semi-molten state impinging onto the substrate. These processes use metal wire that is molten and broken into fine droplets. The coating gun adds thermal energy to bring the materials to a plastic or molten condition and accelerates these materials at high velocities toward the substrate.
